Here's a breakdown of what's involved, emphasizing why professional installation is strongly recommended:
Challenges and Considerations:
* No Original Provisions: 1968 Mustangs didn't come standard with AC. This means there are no factory mounting points, wiring harnesses, or ducts. You'll need to fabricate much of the system's mounting.
* Space Constraints: The engine bay and interior of a classic Mustang are tight. Finding space for the compressor, condenser, evaporator, and all the associated lines and components will require careful planning and potentially some modification to existing parts.
* Firewall Penetration: You'll need to carefully cut and seal holes in the firewall for the evaporator core and lines. This requires precision to avoid compromising the car's structural integrity and preventing leaks.
* Electrical System: The AC system requires significant electrical power. Your existing electrical system might need upgrades to handle the additional load. Improper wiring can lead to electrical fires.
* Refrigerant Handling: AC systems use refrigerants that require specialized equipment and training to handle safely. Improper handling can be dangerous to your health and the environment.
* Vacuum Lines and Control System: The system requires accurate vacuum lines for proper operation and will need connection to either an aftermarket or custom control system.
What You'll Need (Generally):
* Complete AC Kit: This includes the compressor, condenser, evaporator, dryer, expansion valve, hoses, fittings, and control system. Kits specifically designed for 1968 Mustangs are available, but they still require significant installation work.
* Fabrication Tools: Welding equipment, sheet metal, cutting tools, etc., will likely be needed to create custom mounting brackets and modify existing components.
* Electrical Tools and Knowledge: You'll need the tools and skills to safely wire the AC system to your car's electrical system.
* Refrigerant Handling Equipment: This includes vacuum pumps, gauges, and the proper refrigerant.
* Time and Patience: This is a major project that could take days or even weeks to complete.
Best Approach:
Instead of attempting this yourself unless you have extensive experience in automotive mechanics and AC system installation, seriously consider:
* Professional Installation: Find a reputable shop specializing in classic car restoration and AC installation. They have the tools, experience, and knowledge to install the system correctly and safely. This is the most reliable and safest option.
* Pre-Assembled Kits: Some vendors sell pre-assembled kits specifically for '68 Mustangs, but even these need professional-level installation expertise.
Attempting this complex project without the necessary skills and tools could lead to a poorly functioning, inefficient, or even dangerous AC system. The cost of professional installation is a worthwhile investment to ensure a safe and effective result.
